I'm interested in learning about TF-A, OPTEE, are some demos concerning these topics available?Is it possible to debug the CortexA core, through the embedded ST-LINK? I mean working solution, not in theory?What would be limitations debugging very ear...
Hi,I am only a bit familiar with embedded linux. I will develop a demo project with STM32MP157C-DK2 with C language:on M4 side, a sensor(BME280) and a vantilator (5v) are connected. Sensor is to read periodically and three numerical values( temp, hum...
